MemoryMarshal.AsBytes Method

Definition

Namespace:

System.Runtime.InteropServices

Assembly:

System.Runtime.dll

Overloads

AsBytes<T>(ReadOnlySpan<T>)	Casts a ReadOnlySpan<T> of one primitive type, T, to a ReadOnlySpan<Byte>.
AsBytes<T>(Span<T>)	Casts a Span<T> of one primitive type, T, to a Span<Byte>.

AsBytes<T>(ReadOnlySpan<T>)

Source:

MemoryMarshal.cs

Casts a ReadOnlySpan<T> of one primitive type, T, to a ReadOnlySpan<Byte>.

public:
generic <typename T>
 where T : value class static ReadOnlySpan<System::Byte> AsBytes(ReadOnlySpan<T> span);

public static ReadOnlySpan<byte> AsBytes<T> (ReadOnlySpan<T> span) where T : struct;

static member AsBytes : ReadOnlySpan<'T (requires 'T : struct)> -> ReadOnlySpan<byte> (requires 'T : struct)

Public Shared Function AsBytes(Of T As Structure) (span As ReadOnlySpan(Of T)) As ReadOnlySpan(Of Byte)

Type Parameters

T

The type of items in the read-only span.

Parameters

span

ReadOnlySpan<T>

The source slice to convert.

Returns

ReadOnlySpan<Byte>

A read-only span of type Byte.

Exceptions

ArgumentException

T contains managed object references.

OverflowException

The Length property of the new ReadOnlySpan<T> would exceed Int32.MaxValue

Remarks

T cannot contain managed object references. The AsBytes method performs this check at runtime and throws ArgumentException if the check fails.

Caution

This method provides a raw binary projection over the original span, including over any private instance fields and other implementation details of type T. Callers should ensure that their code is resilient to changes in the internal layout of T.

AsBytes<T>(Span<T>)

Source:

MemoryMarshal.cs

Casts a Span<T> of one primitive type, T, to a Span<Byte>.

public:
generic <typename T>
 where T : value class static Span<System::Byte> AsBytes(Span<T> span);

public static Span<byte> AsBytes<T> (Span<T> span) where T : struct;

static member AsBytes : Span<'T (requires 'T : struct)> -> Span<byte> (requires 'T : struct)

Public Shared Function AsBytes(Of T As Structure) (span As Span(Of T)) As Span(Of Byte)

Type Parameters

T

The type of items in the span.

Parameters

span

Span<T>

The source slice to convert.

Returns

Span<Byte>

A span of type Byte.

Exceptions

ArgumentException

T contains managed object references.

OverflowException

The Length property of the new ReadOnlySpan<T> would exceed Int32.MaxValue

Remarks
